This study was designed to compare the effectiveness of fluconazole vs. itraconazole as mainte-nance therapy for AIDS-associated cryptococcal meningitis. HIV-infected patients who had been successfully treated (achieved negative culture of CSF) for a first episode of cryptococcal meningitis were randomized to receive fluconazole or itraconazole, both at 200 mg/d, for 12 months. The study was stopped prematurely on the recommendation of an independent Data Safety and Monitoring Board. At the time, 13 (23%) of 57 itraconazole recipients had experienced culture-positive relapse, compared with 2 relapses (4%) noted among 51 fluconazole recipients (P = .006). The factor best associated with relapse was the patient having not received flucytosine during the initial 2 weeks of primary treatment for cryptococcal disease (relative risk = 5.88; 95% confidence interval, 1.27-27.14; P = .04). Fluconazole remains the treatment of choice for maintenance therapy for AIDS-associated cryptococcal disease. ...

Abstract. Cryptococcal meningitis may have long-term morbidity and requires a permanent cerebrospinal fluid shunt. This study aimed to evaluate the risk factors and create a predictive model for permanent shunt treatment in cryptococcal meningitis patients. This was a retrospective analytical study conducted at Khon Kaen University. The study period was from January 2005 to December 2015. We enrolled all adult patients diagnosed with cryptococcal meningitis. Risk factors predictive for permanent shunting treatment were analyzed by multivariate logistic regression analysis. There were 341 patients diagnosed with cryptococcal meningitis. Of those, 64 patients (18.7%) were treated with permanent shunts. There were three independent factors associated with permanent shunt treatment. The presence of hydrocephalus had the highest adjusted odds ratio at 56.77. The resulting predictive model for permanent shunt treatment (y) is (−3.85) + (4.04 × hydrocephalus) + (2.13 × initial cerebrospinal fluid (CSF)

This is a phase III randomized trial to evaluate whether sertraline when added to standard amphotericin-based therapy for cryptococcal meningitis, will lead to improved survival . Cryptococcal meningitis diagnosis will be made via CSF cryptococcal antigen (CRAG) at time of lumbar puncture (LP) with confirmation by CSF culture. After informed consent, subjects that meet eligibility requirements will be able to enter study. A non-randomized phase I dose-escalation study will first be conducted to help optimize dosing for a larger randomized phase II study.. Phase III Design: Subjects will be randomized to standard induction therapy with masked placebo or sertraline at 400mg/day. We will use a permutated block randomization in a 1:1 allocation (n=275 per arm). Total anticipated enrollment: 550 subjects. ...
CORRESPONDENCE. Responding to the evidence for improved treatment for cryptococcal meningitis in resource-limited settings. To the Editor: The World Health Organization (WHO) issued the first evidence-based treatment guidelines for cryptococcal meningitis in December 2011.1 Although its incidence has decreased with increased access to antiretroviral therapy, cryptococcal meningitis remains a major cause of death in people with HIV/AIDS, with over 500 000 deaths every year in sub-Saharan Africa. It is a leading cause of death in the Médecins sans Frontières (MSF) HIV/AIDS programmes in Africa.2,3. The preferred treatment in the WHO guidelines combines amphotericin B injectable with oral solid formulations of either flucytosine or fluconazole. The liposomal injectable form of amphotericin B is also indicated as an alternative to conventional amphotericin B because it is associated with fewer side-effects. However, it is acknowledged that this option is currently too expensive for routine use in ...
EDITORIAL. Cryptococcal meningitis - a neglected killer. In this issue of the SAMJ, Lessells et al.1 highlight the unacceptably high mortality due to HIV-associated cryptococcal meningitis (CM) in routine clinical practice in South Africa. CM is now the most common cause of adult meningitis in much of central and southern Africa, accounting for 63% of all microbiologically confirmed cases in the largest published series.2 There are an estimated 720 000 cases annually in sub-Saharan Africa, leading to 504 000 deaths;3 expanding access to antiretroviral therapy (ART) has not yet led to a decline in these numbers.4 In research settings in South Africa, utilising optimal amphotericin B-based treatments, acute mortality of CM is between 24 and 37%.5,6 Lessells et al. suggest that, in routine care settings, mortality rates are higher.1 From their study conducted at Hlabisa Hospital in rural Kwazulu-Natal, they report 41% in-hospital mortality (all of which deaths occurred within 30 days of admission), ...

In a presentation today at the AIDS-Associated Mycoses Meeting, scientists from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), showed that they could effectively treat mice infected with cryptococcal meningitis in two experiments using an orally administered lipid-crystal ...
In AIDS patients with cryptococcal meningitis, a correlation has been found between early death and elevated intracranial pressure. Since dexamethasone has been found to reduce intracranial pressure resulting from other forms of meningitis, it may be of benefit in AIDS patients with cryptococcal meningitis.. Patients are randomized to receive dexamethasone or placebo every 6 hours for 72 hours (days 1 through 3). Additionally, standard antifungal therapy with amphotericin B and flucytosine is given for 2 weeks, followed by fluconazole for 8 weeks. Lumbar punctures will be performed daily on days 1 through 3, on days 7 and 14, and at week 10. ...

The clinical symptoms of CM are nonspecific, and neuroimaging characteristics are variable. Herein, we present a case of a senile female with CM that was once misdiagnosed as cerebral infarction. Her condition worsened and she developed hydrocephalus. No apparent predisposing factors of CM were reported in this patient. The diagnosis of CM was definitely made after India ink staining of cerebrospinal fluid
Before the introduction of the antifungal amphotericin B therapy in the mid-1950s for cryptococcal meningitis, the mortality rate was 100% for these cases. Published studies from the USA and Europe indicate that while current treatment regimens are still associated with acute mortality rates during initial therapy, the 12 month survival rates among all patients with maintenance therapy are significantly improved and a large proportion of patients do extremely well on maintenance antifungal therapy.4-6 8-13 The introduction of antiretroviral treatment regimens has further improved morbidity and mortality from fungal infections in AIDS patients in the west.. Our observational study of cryptococcal meningitis in AIDS patients, one of the largest so far from Central Africa, provides further insight into the clinical presentation, natural history, and outcome of this disease in the sub-Saharan African situation. The results of this study substantiates our clinical observations over the past decade at ...
The Advancing Cryptococcal Meningitis Treatment for Africa (ACTA) trial funded by the Medical Research Council (UK) and ANRS (France) has highlighted the benefits of new therapeutic regimens in the treatment of cryptococcal meningitis, a frequent and severe opportunistic disease in patients living with HIV. In light of these findings, reported in the 15 March 2018 issue of the New England Journal of Medicine, the WHO has changed its guidelines regarding treatment of this fungal infection.

Abstract : ABSTRACT Cryptococcal meningitis has emerged as a leading cause of infectious morbidity and mortality in patients with AIDS. Among the human immunodeficiency virus (HIV)-seropositive subjects, cryptococcal meningitis is the second most common cause of opportunistic neuro-infection. Cryptococcal meningitis occurs in non-HIV patients who are immune deficient due to diabetes, cancer, solid organ transplants, chemotherapeutic drugs, hematological malignancies etc and rarely in healthy individuals with no obvious predisposing factors. Diagnosis of cryptococcal meningitis is fairly straightforward once the diagnosis is considered in the differential diagnosis of chronic meningitis. Treatment of a patient with cryptococcal infection is a challenge for both the physician and the patient, but rewarding, as many would recover with timely and adequate antifungal therapy. Keywords: Human Immunodeficiency Virus, Cryptococcal Infection ...
Both these studies also demonstrated that, with appropriate monitoring, conventional amphotericin B is reasonably well tolerated, with drug discontinuations in 3% of patients in the first 2 weeks in the Mycoses Study Group trial [21]. Saline and fluid loading equivalent to 1 litre normal saline daily should be given unless contraindicated, to minimize nephrotoxicity [63], and electrolytes replaced as required. Anaemia, secondary to suppression of erythropoietin transcription [64], is also a predictable side effect of amphotericin B [65-67]. This may be more clinically significant in populations with lower baseline haemoglobin levels, and where transfusion, when occasionally needed, is difficult.. Flucytosine, at the historically low daily dose of 100 mg/kg, was also well tolerated without real-time drug level monitoring in either trial. A substudy of the Thai trial comparing oral and intravenous flucytosine at the same daily dosage of 100 mg/kg has provided some insight into this observation. In ...

Objective:To study the characteristic,diagnosis and therapeutics of cryptococcal meningitis (CM) associated with systemic lupus erythematosus (SLE) and to improve the relevant diagnostic and therapeutics of the disease. Methods:8 patients with SLE, complicated by CM had been included in the study. The data of clinical manifestations,cerebrospinal fluid(CSF) findings and the whole process of diagnosis and treatment were reviewed. Results: The complication in SLE was always clinically latent. The nonspecific clinical and CSF laboratory findings may lead to misdiagnosis such as lupus encephalopathy or tuberculous meningitis. In our patients, the period from initiation of disease to diagnosis definitely was about 2-16 weeks. The rate of misdiagnosis was 50%. Timely and repeatedly CSF cryptococcus latex agglutination, culture or smear is the key to diagnosis. Antifungal therapy mainly with amphotericin B was effective and the efficiency was 100%. Conclusion:The early diagnosis and effective antifungal
The therapy for cryptococcal meningitis in patients with the acquired immunodeficiency syndrome (AIDS) is still unsatisfactory. Although other populations generally respond well to treatment with amphotericin B and flucytosine, patients with AIDS have a markedly lower cure rate (1). Moreover, after the initial therapy, long-term maintenance treatment with an antifungal agent is mandatory, because of the high frequency of recurrences. Weekly amphotericin B therapy has been recommended for this purpose, but Zuger and colleagues (2) show that some patients have relapses despite the administration of maintenance doses of the drug. On the other hand, the severity of side effects (including ...

Ruxolitinib is a highly potent janus kinase inhibitor that places its users at risk for various bacterial infections and viral reactivation. However new reports are also emerging that suggest greater immunosuppression and risk for fungal disease. We report the case of a 51 year-old veteran from Guam, treated with ruxolitinib for polycythemia vera, who developed disseminated histoplasmosis and concurrent cryptococcal meningitis. This case draws attention to the degree of immunosuppression that may be seen with this drug and the need for heightened vigilance for opportunistic infections in those treated with inhibitors of janus kinase/signal transducers and activators of transcription (JAK/STAT) such as ruxolitinib.

Objectives: Cryptococcus species are associated with invasive fungal infections in immunosuppressed individuals. The clinical significance of low titer cryptococcal antigen (CrAg) by lateral flow assay is frequently uncertain. We investigated the correlation of low CrAg titers with disease in an immunocompromised patient population.. Methods: Patients with first-time positive CrAg results with low serum titers (≤1:10) at two medical centers (Los Angeles, CA) from April 2014-July 2018 were included. Age-matched controls with high (≥1:20) and negative titers were selected. We extracted medical records for pertinent clinical, radiologic, and laboratory data for cryptococcal disease.. Results: From 2,196 serum samples submitted for CrAg testing, 96 cases were included (32 each in low titer, high titer, and negative titer groups). One or more immunocompromising condition was identified in 95% of patients, including HIV infection (45%), solid organ transplant (26%), and cirrhosis (22%). Pulmonary ...
The case below of systemic cryptococcal infection and meningitis, an opportunistic fungal infection, in a pwMS on fingolimod is one of many cases reported worldwide. The problem with fingolimod is that you cant derisk the risk of opportunistic infections. All cases of opportunistic infection on fingolimod, to the best of my knowledge, have occurred in pwMS with lymphocyte counts above 200/mm3 or 0.2x109/L (the action level ti disruot dosing in the EU). In addition, infections in pwMS on fingolimod are not linked to the peripheral lymphocyte counts. Therefore, the only way to deal with the opportunistic infection risk on fingolimod is to remain vigilant and be aware of symptoms suggsetive of an infection. In the case of cryptococcal meningitis this may be very subtle symptoms; for example a non-specific headache or visual symptoms. The reason why cryptococcal infection is very indolent is simply because people who are immunosuppressed are unable to mount a vigorous immune response against the ...
Diagnosis of invasive cryptococcal infection in apparently nonimmunocompromised patients is difficult and often delayed. Human immunodeficiency virus- (HIV-) negative patients with decompensated hepatic cirrhosis might be at high risk of cryptococcal infection. We report here an 82-year-old Japanese female with end-stage hepatic failure and undergoing renal dialysis, hospitalized with septic shock-like symptoms. The patient had had hepatitis B virus (HBV) infection in the past. She survived only 4 days following admission. During hospitalization, she was found to have pleural effusion and ascites.|i| Cryptococcus neoformans|/i| was obtained from blood culture but not from pleural effusion culture. Consequently, the patient was diagnosed as having invasive cryptococcosis in association with HBV-related hepatic cirrhosis. Unfortunately, the patient died prior to receiving antifungal agents. Twelve Japanese cases of hepatic cirrhosis-related invasive cryptococcal infection, consisting of previously
Cryptococcal meningitis is common in sub-Saharan Africa. Given the need for data for a rapid, point-of-care cryptococcal antigen (CRAG) lateral flow immunochromatographic assay (LFA), we assessed diagnostic performance of cerebrospinal fluid (CSF) culture, CRAG latex agglutination, India ink microscopy, and CRAG LFA for 832 HIV-infected persons with suspected meningitis during 2006-2009 (n = 299) in Uganda and during 2010-2012 (n = 533) in Uganda and South Africa. CRAG LFA had the best performance (sensitivity 99.3%, specificity 99.1%). Culture sensitivity was dependent on CSF volume (82.4% for 10 μL, 94.2% for 100 μL). CRAG latex agglutination test sensitivity (97.0%-97.8%) and specificity (85.9%-100%) varied between manufacturers. India ink microscopy was 86% sensitive. Laser thermal contrast had 92% accuracy (R = 0.91, ...
The study by Baughman and colleagues comprises 2 parts. The first part was a retrospective analysis of 51 patients, the results of which yielded 100% sensitivity and 100% specificity. The second part was a prospective study of 220 patients. 15 were positive for cryptococcal antigen in their BAL fluid, but only 8 of them had culture-proven cryptococcal pneumonia. On the basis of a 3.6% prevalence of cryptococcal infection in this group of patients, a negative predictive value of 100% was calculated. The authors also calculated a positive predictive value of 53% to 67% depending on the cut-point titer of antigen used. Because of the 7 false-positive antigen tests obtained from the prospective study, all antigen-positive and 10 antigen-negative BAL specimens were retested after they were stored at -80 °C for at least 3 months. All culture-positive specimens were antigen positive, but none of the 7 initially false-positive specimens remained positive, thus providing a 100% sensitivity and 100% ...

Results: 57 patients were studied. Cryptococcus neoformans var grubii molecular type VN1 caused 70% of infections; C. gattii accounted for the rest. Most patients did not have underlying disease (81%), and the rate of underlying disease did not differ by infecting species. 11 patients died while in-patients (19.3%). Independent predictors of death were age ≥ 60 years and a history of convulsions (odds ratios and 95% confidence intervals 8.7 (1 - 76), and 16.1 (1.6 - 161) respectively). Residual visual impairment was common, affecting 25 of 46 survivors (54.3%). Infecting species did ...
CSF PCR is the standard diagnostic technique used in resource-rich settings to detect pathogens of the CNS infection. However, it is not currently used for routine CSF testing in China. Knowledge of CNS opportunistic infections among people living with HIV in China is limited. Intensive cerebrospiral fluid (CSF) testing was performed to evaluate for bacterial, viral and fungal etiologies. Pathogen-specific primers were used to detect DNA from cytomegalovirus (CMV), herpes simplex virus (HSV), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), human herpesvirus 6 (HHV-6) and John Cunningham virus (JCV) via real-time polymerase chain reaction (PCR). Cryptococcal meningitis accounted for 63.0% (34 of 54) of all causes of meningitis, 13.0% (7/54) for TB, 9.3% (5/54) for Toxoplasma gondii. Of 54 samples sent for viral PCR, 31.5% (17/54) were positive, 12 (22.2%) for CMV, 2 (3.7%) for VZV, 1 (1.9%) for EBV, 1 (1.9%) for HHV-6 and 1 (1.9%) for JCV. No patient was positive for HSV.

Description: Meningeal inflammation produced by CRYPTOCOCCUS NEOFORMANS, an encapsulated yeast that tends to infect individuals with ACQUIRED IMMUNODEFICIENCY SYNDROME and other immunocompromised states. The organism enters the body through the respiratory tract, but symptomatic infections are usually limited to the lungs and nervous system. The organism may also produce parenchymal brain lesions (torulomas). Clinically, the course is subacute and may feature HEADACHE; NAUSEA; PHOTOPHOBIA; focal neurologic deficits; SEIZURES; cranial neuropathies; and HYDROCEPHALUS.

Cryptococcal meningitis remains the leading cause of adult meningitis in Sub-Saharan Africa. Immune Reconstitution Inflammatory Syndrome (IRIS) following anti-retroviral therapy (ART) initiation is an important complication. Here we report the first documented case of a IRIS reaction presenting as an ischemic stroke. A 38 year old newly diagnosed HIV-infected, ART naive Malawian male presented to a tertiary referral hospital in Blantyre, Malawi with a 2 week history of headache. A diagnosis of cryptococcal meningitis was made and the patient was started on 1200 mg fluconazole once daily and flucytosine 25 mg/kg four times daily as part of the Advancing Cryptococcal Treatment for Africa (ACTA) clinical trial. There was an initial clinical and microbiological response to anti-fungal treatment and anti-retroviral therapy was started at week 4. The patient re-presented 16 days later with recurrence of headache, fever, and a sudden onset of left sided weakness in the context of rapid immune reconstitution;
Cryptococcal antigenemia may precede development of cryptococcal meningitis and death among patients with advanced HIV infection. Among 200 retrospectively and randomly selected ART-na ve patients with CD4 counts < 100 cells/ l from Guinea-Bissau, 20 (10%) had a positive cryptococcal antigen test. Self-reported headache and fever were predictors of a positive test, while cryptococcal antigenemia was a strong predictor of death within the first year of follow-up, MRR 2.22 (95% CI: 1.15-4.30). Screening for cryptococcal antigenemia should be implemented for patients with advanced HIV in Guinea-Bissau. Pre-emptive anti-fungal therapy should be initiated prior to ART-initiation if the screening is positive.
About your speaker. Dr Christina Chang is an Infectious Diseases Physician at the Alfred Hospital, Melbourne and NHMRC Early Career Fellow at Monash University. She continues to expand work derived from her PhD where she established a clinical cohort of HIV-infected patients co-infected with cryptococcal meningitis (CM) in Durban, South Africa, exploring the immunopathogenesis of cryptococcosis-associated immune reconstitution inflammatory syndrome (C-IRIS). She will discuss clinical, immunological, and mycological aspects of CM and C-IRIS and also update on new insights in IRIS more generally. A clinician scientist, Christina enjoys a mix of clinical and laboratory research in a broad range of areas including HIV pathogenesis, circadian biology and fungal infections but derives most joy from her patients..

Acute/subacute cerebral infarction (ASCI) in HIV-negative cryptococcal meningoencephalitis (CM) adults has rarely been examined by a series of MRI-based follow-up study. We studied a series of MRI follow-up study of CM adults and compared the clinical characters of those with ASCI and those without ASCI. The clinical characteristics and a series of brain MRI findings of seven CM adults with ASCI were enrolled for analysis. The clinical characteristics of another 30 HIV-negative CM adults who did not have ASCI were also included for a comparative analysis. The seven HIV-negative CM adults with ASCI were four men and three women, aged 46-78 years. Lacunar infarction was the type of ASCI, and 86% (6/7) of the ACSI were multiple infarctions distributed in both the anterior and posterior cerebrovascular territories. The seven CM patients with ASCI were significantly older and had a higher rate of DM and previous stroke than the other 30 CM adults without ASCI. They also had a higher incidence of
In a multicenter study comparing DIFLUCAN (200 mg/day) to amphotericin B (0.3 mg/kg/day) for treatment of cryptococcal meningitis in patients with AIDS, a multivariate analysis revealed three pretreatment factors that predicted death during the course of therapy: abnormal mental status, cerebrospinal fluid cryptococcal antigen titer greater than 1:1024, and cerebrospinal fluid white blood cell count of less than 20 cells/mm3. Mortality among high risk patients was 33% and 40% for amphotericin B and DIFLUCAN patients, respectively (p=0.58), with overall deaths 14% (9 of 63 subjects) and 18% (24 of 131 subjects) for the 2 arms of the study (p=0.48). Optimal doses and regimens for patients with acute cryptococcal meningitis and at high risk for treatment failure remain to be determined. (Saag, et al. N Engl J Med 1992; 326:83-9.). ...
The pathogenic species of Cryptococcus are a major cause of mortality owing to severe infections in immunocompromised as well as immunocompetent individuals. Although antifungal treatment is usually effective, many patients relapse after treatment, and in such cases, comparative analyses of the genomes of incident and relapse isolates may reveal evidence of determinative, microevolutionary changes within the host. Here, we analyzed serial isolates cultured from cerebrospinal fluid specimens of 18 South African patients with recurrent cryptococcal meningitis. The time between collection of the incident isolates and collection of the relapse isolates ranged from 124 days to 290 days, and the analyses revealed that, during this period within the patients, the isolates underwent several genetic and phenotypic changes. Considering the vast genetic diversity of cryptococcal isolates in sub-Saharan Africa, it was not surprising to find that the relapse isolates had acquired different genetic and ...
Cryptococcus neoformans is a pathogenic fungus that causes meningitis worldwide, particularly in human immunodeficiency virus (HIV)-infected individuals. Although amphotericin B is the gold standard treatment for cryptococcal meningitis, the toxicity and inconvenience of intravenous injection emphasize a need for development of new anticryptocccal drugs. Recent data from humans and animal studies suggested that a nutrient-deprived host environment may exist in cryptococcal meningitis. Thus, a screening assay for identifying fungicidal compounds under nutrient-deprived conditions may provide an alternative strategy to develop new anticryptococcal drugs for this disease. A high-throughput fungicidal assay was developed using a profluorescent dye, alamarBlue, to detect residual metabolic activity of C. neoformans under nutrient-limiting conditions. Screening the Library of Pharmacologically Active Compounds (LOPAC) with this assay identified a potential chemical scaffold, 10058-F4, that exhibited ...
In Europe before the advent of the acquired immunodeficiency syndrome (AIDS), fatal cases of infection with Cryptococcus neoformans resembling acute meningitis were rarely described and never in young adults. However, rapidly fatal cryptococcal meningitis in young Africans has been known to exist in central Africa for at least 30 years, mainly in the lower area of the Congo River basin. Cases have been reported in this area since 1953, particularly in young patients during the 1950s. It is also known that central African AIDS patients frequently suffer from cryptococcosis, and there is a possibility that earlier clinical reports of encephalitis were actually fatal cases of AIDS in young Africans. It appears possible that the central part of the African continent is the area where human immunodeficiency virus originated. Rapidly fatal cryptococcal meningitis has existed in central Africa for more than 30 years, mainly in the lower area of the Congo River basin. Cases have been reported in that area since
To treat thrush (yeast infection of the mouth and throat), the recommended adult dose is 100 mg taken by mouth once daily for at least 2 weeks.. To treat esophageal candidiasis (yeast infection of the tube leading to the stomach), the recommended adult dose ranges from 100 mg to 200 mg taken daily for at least 3 weeks. Fluconazole must be taken for at least 2 weeks after the symptoms of the infection resolve to prevent the infection from returning.. To treat yeast infection that has spread throughout the body (disseminated yeast infection), the recommended adult dose of fluconazole is 200 mg to 400 mg once daily, for at least 4 weeks. Again, this medication must be taken for at least 2 weeks after the symptoms of the infection resolve to prevent the infection from returning.. To treat cryptococcal meningitis, the recommended dose of fluconazole is 200 mg to 400 mg once daily. Fluconazole should be taken for at least 10 weeks when treating this condition.

Objective: Despite the recognition of Cryptococcus neoformans as a major cause of meningitis in HIV-infected adults in sub-Saharan Africa, little is known about the relative importance of this potentially preventable infection as a cause of mortality and suffering in HIV-infected adults in this region. Design: A cohort study of 1372 HIV-1-infected adults, enrolled and followed up between October 1995 and January 1999 at two community clinics in Entebbe, Uganda. Methods: Systematic and standardized assessment of illness episodes to describe cryptococcal disease and death rates. Conclusions: Cryptococcal disease was diagnosed in 77 individuals (rate 40.4/1000 person-years) and was associated with 17% of all deaths (77 out of 444) in the cohort. Risk of infection was strongly associated with CD4 T cell counts 6cells/l (75 patients) and World Health Organization (WHO) clinical stage 3 and 4 (68 patients). Meningism was present infrequently on presentation (18%). Clinical findings had limited ...
OBJECTIVE: Indonesia has a concentrated but rapidly growing HIV epidemic. We examined the effect of HIV on causative organisms, clinical features and prognosis of adult meningitis. DESIGN: A prospective cohort study. METHODS: All adult patients at a referral hospital who underwent cerebrospinal fluid examination for suspected meningitis were examined for HIV and included in a prospective cohort study. Microbiological testing was done for common bacterial pathogens, mycobacteria and fungi. Patients were followed for at least 6 months, and logistic regression models were used to identify risk factors for mortality. RESULTS: Among 185 patients who mostly presented with subacute meningitis, 60% were male and the median age was 30 years. HIV infection was present in 25% of the patients; almost two-thirds were newly confirmed, and all presented with severe immunosuppression (median CD4 cell count 13/microl, range 2-98). One-third of HIV-infected patients had cryptococcal meningitis whereas two-thirds ...
4) Immune reconstitution inflammatory syndromes (IRIS): a group of syndromes casued by the inflammation generated by a reconstituted immune system in the first 4-8 weeks after starting on combined antiretroviral therapy. Usually seen in HIV patients with CD4 counts less than 50 being started on therapy for the first time in the setting of an opportunistic infection. Typically presents as a paradoxical worsening of course in patients with HIV encephalitis, cryptococcal meningitis toxoplamsamosis encephalitis and PML. ...

Flucytosine is an antifungal agent which is useful in treating patient with cryptococcal meningitis, fungal infection, systemic candidiasis and yeast infection.
Infection is initiated by inhalation of the yeast cells. The primary pulmonary infection may be asymptomatic or may mimic influenza like respiratory infection often resolving spontaneously. In immune-compromised patients with impaired T cell immunity, the yeasts may multiply and disseminate to other parts of the body but preferentially to the central nervous system (neurotropic), causing cryptococcal meningitis. Other common sites of dissemination include the skin, adrenals, bone, eye and prostate gland. The inflammatory reaction is usually minimal or granulomatous.. Virulence Factors of Cryptococcus neformans ...
Brain infections such as meningitis and encephalitis are highly debilitating diseases, and an accurate diagnostic is essential to give patients the best treatment available. For cryptococcal meningitis, clinical trials focus on prevention, for an early diagnosis, and novel ways to use existing treatments or repurpose old drugs.

So here at Princess Marina Hospital, probably the largest public hospital in Botswana, there are often problems with the availability of medicine, or of certain medical instruments, even very common ones. Last week, we ran out of amphotericin, which is a drug we use to treat cryptococcal meningitis - thats an infection in the cerebrospinal fluid that surrounds your brain and spinal cord. Its the type of thing that we diagnose with an LP, which I described in previous posts. Because a lot of people have HIV and AIDS here, a lot more here come down with meningitis than in the states - some of it is due to TB, some bacterial, some bacterial, but more often than not, its due to cryptococcus. And amphotericin is really the only option they have in Botswana to treat it. Alternatively, you can use a whopping dose of fluconazole, but it doesnt work as well, and we also ran out of that for a few days last weekend. As a result, all these people in the hospital (and in the clinics probably) had no ...
Three previously normal patients with cryptococcal meningitis had intracranial lesions on computed tomography and magnetic resonance imaging that persisted for ,5 years after successful cure with antifungal drugs. Persistence of lesions on neuroimaging should not be misinterpreted as evidence of active cryptococcosis.. ...

HIV-related opportunistic infections that can effect the nervous system. These include neuropathy, dementia, cryptococcal meningitis or toxoplasmic encephalitis, and progressive multifocal leukoencephalopathy.
People with HIV used to have a different outlook than they currently do. The virus often progressed to AIDS, which is the final stage of HIV, and premature death. Advances in medication are now allowing people with HIV to live longer and to remain in general good health. Having HIV increases the risk of developing several other health conditions. These include kidney disease, cryptococcal meningitis, and certain lymphomas. Treating these other diseases can be bei Psoriasis kann HIV positiv challenging because of the powerful drugs that people with HIV must take every day.. Fears of drug interactions are very real. Because people with HIV already have a compromised immune system, side effects from other drugs can be amplified. These concerns even extend to psoriasis, a chronic skin condition and autoimmune disease. Psoriasis is especially common in people who have HIV. Psoriasis treatment is more complicated if you also have HIV. Psoriasis causes thick, scaly patches or plaques to appear on the ...
It is not uncommon to encounter in a hospital emergency room in San Francisco, Atlanta, New York City, or Washington, DC, a young man or woman with the diagnosis of life-threatening cryptococcal meningitis or pneumonia caused by Pneumocystis jirovecii as the first manifestation of HIV infection. How could this be possible in 2010, fully 3 decades into the epidemic in the United States? How could this be possible in a country that prides itself on the widespread availability of HIV testing and treatment options? How could this be possible in a country with broad access to health messages and a plethora of communication tools? How could this be possible in one of the richest countries on earth?. The answers to these questions are sobering. HIV in the United States is currently an invisible epidemic, largely confined to vulnerable and disenfranchised populations. It has disappeared from the public discourse. The prevailing perception is that HIV is a problem of the past, with few new infections and ...
The JC virus, or John Cunningham virus, is a member of the polyomavirus family. When youre exposed to it as a kid or young adult, you might not even notice it, or you might notice cold-like symptoms which are self-limiting. Not a huge deal at all. You get infected, you make antibodies, life goes on. As long as youre immunocompetent. But thats not the case in patients with impaired cellular immunity, as in cases of Hodgkins lymphoma (HL).. Although the gold standard for diagnosis is brain biopsy, you dont need tissue to make the diagnosis of PML. In an immunocompromised patient with progressive neurologic changes, youll always need the MRI. This can exclude opportunistic processes like toxoplasmosis, cryptococcal meningitis, or CNS lymphoma, but will also be important to confirm the presence of white matter disease, which may or may not have enhancement 10-20% of the time, and may or may not have mass effect. Our patient had faint enhancement, as you can see from the images on the blog. Once ...
My experiences at Mbingo Baptist Hospital in Cameroon have undoubtedly been some of the most impactful in my career thus far. I spent my days running the pediatric and internal medicine wards, rounding in the ICU, and helping with difficult clinic patients brought to the wards throughout the day. Medical experiences were extensive, including managing peritoneal dialysis in several children with complicated malaria, TB and cryptococcal meningitis, countless AIDs complications, Burkitts lymphoma, breast cancer, repercussions of country medicine, and of course, managing constipation, hypertension and diabetes in creative ways. There are always surprises at the hospital entrance, given people journey up to 9 hours to seek care with us, often in critical condition. Peer-to-peer consults over puzzling cases make things even more interesting as well. It was also great teaching national residents and nursing staff at the bedside and in formal lectures. Getting to know everyone has been a blessing, ...
